Hi all, I've conceived a medium SSTO this morning based on an aircraft I really like, it is absolutely inefficient but should be able to reach a 200x200 km orbit. It's only about the look. My main problem is due to personnal choice, appearance and aerodynamic reasons I tried to place 4 Whiplash and 4 Nerv in tandem but the Whiplash explode due to overheating each time. When I'm making ground test on the runway I can run the Nerv at full power with just the ramjets overheating just a bit, but when I'm reaching 15-16 km of altitude and ignitiate the Nerv all ramjets explode istantly due to overheating. I've tried to shut down the Whiplash first, back the throttle to idle then ignitiate the Nerv and spool them up slowly but the result is still the same. I have place two large radiator on the engines section to see if it would make a difference, same result : Ka-boom! I remember seeing some SSTO concepts here and on KerbalX where peoples succeed to built those tandem Nerv-Whiplash engines, even calling them something like "Next Generation Propulsion" or "Nuclear Turbo-ramjet" but I can't find them in the database. Could you help me by explaining how you build them ?
